Hi Steven,
Right you are (63,700!) ... I don't know what search string I used
before, but clearly not this rather obvious one .. duh.

I will - thanks. I have tools for 1D, I mostly am interested in 2D
optimization at this point, mostly as a way to verifying some results
I am calculating.
Hopefully SciPy will provide a nice simple interface to help me do
this.
Thanks,
Esmail
